xVictron Skylla-i 24/80 (1+1) 230V Battery Charger
The Victron Skylla-i 24/80 (1+1) is a high-power, three-stage battery charger designed for 24V battery systems requiring up to 80A of charge current. The (1+1) configuration provides a dedicated 4A output for a second battery bank, making it well suited to marine, vehicle, industrial and off-grid installations where a service battery and a starter or auxiliary battery must be charged simultaneously from a single unit.
Key Features
- 80A primary output for 24V battery banks, with a separate 4A output for a second battery bank in the (1+1) configuration.
- Three-stage adaptive charging algorithm (bulk, absorption, float) with an optional storage mode to maintain battery health during long periods of inactivity.
- Compatible with a wide range of battery chemistries including flooded lead-acid, AGM, gel and lithium-ion (with appropriate BMS).
- Synchronised parallel operation: multiple Skylla-i units can be connected in parallel to increase total charge current for larger battery banks.
- VE.Bus connectivity allows integration with other Victron equipment, enabling remote monitoring and configuration via the Victron GX ecosystem.
- Adjustable charge voltage and current settings, allowing the charger to be configured precisely for the battery type and installation requirements.
- Built-in temperature compensation adjusts charge voltage automatically to protect batteries in environments with variable ambient temperatures.
- 230V AC input, suitable for shore power, generator or mains supply connections across the UK and EU.
Product Overview
The Skylla-i range sits at the professional end of Victron's charger lineup. The 24/80 model delivers 80A into a 24V bank, which is sufficient for charging large lead-acid or lithium battery banks found in commercial vehicles, narrowboats, yachts, off-grid cabins and industrial standby systems. The (1+1) designation means the unit simultaneously provides a 4A trickle charge to a second battery, typically a starter or bow-thruster battery, without requiring a separate charger or battery-to-battery device.
VE.Bus connectivity is a key practical advantage for professional installers. It allows the Skylla-i to communicate directly with Victron Quattro inverter/chargers, Cerbo GX units and other VE.Bus-compatible devices. This means charge current can be managed dynamically in response to available AC input, and the charger can be monitored and configured remotely through VictronConnect or the VRM portal. For installations where AC input is shared between an inverter and the charger, this coordination prevents overloading the supply.
The unit accepts 230V AC input, making it directly compatible with UK and European shore power and generator outputs. Parallel operation is supported natively, so where 80A is insufficient, two or more Skylla-i units can be synchronised to share the load across a larger battery bank without requiring additional control hardware.

What Is Included
- 1 x Victron Skylla-i 24/80 (1+1) 230V battery charger
Installation Notes
Installation should be carried out by a qualified electrician or experienced marine/electrical engineer familiar with battery charging systems. The unit connects to a 230V AC supply and to a 24V DC battery bank; both connections must be correctly fused and cabled to the appropriate cross-section for the current ratings involved. For marine installations, compliance with relevant ISO or ABYC wiring standards is recommended. Where the Skylla-i is integrated into a Victron VE.Bus system alongside an inverter/charger, ensure the combined AC input load does not exceed the capacity of the supply or generator. Lithium battery installations require a compatible BMS with charge enable/disable functionality.
